Yibo Cai updated ARROW-11368:
-----------------------------
Description: Mode and quantile kernels support returning multiple values
and always return array to hold multiple values. If only one value is required,
an array of size 1 is returned. It's better to return a scalar instead in this
case. (was: Mode and quantile kernels support returning multiple values and
always return vector to hold multiple values. If only one value is required, a
vector of size 1 is returned. It's better to return a scalar instead in this
case.)
